SCRAPER.

SPECIFICATION forming part of Letters Patent No. 653,11 5, dated July 3, 1900.

Application filed October 24, 1899- $e 1 ialNo, 734,671. (No model.)

To all whom it may concern:

Be it known that I, TVILLIAM HOWELL ONION, of New Orleans, in the parish of Orleans and State of Louisiana, have invented a new and Improved Scraper, of which the following is a full, clear, and exact description.

This invention relates to a scraper for grading and like purposes; and the purpose of the invention is to provide a scraper which may be more easily dumped and handled in other respects, to which end I provide certain mechanism for holding a bucket in active position and forraisingit, so as to carry its load to the dump, and then for readily and quickly inverting the bucket to spill its contents.

This specification is the disclosure of one form of my invention, while the claims disclose the actual scope thereof.

Reference is to be had to the accompanying drawings, forminga part of this specification, in which similar characters of reference indicate corresponding parts in all the views.

Figure 1 is a side elevation of the invention. Fig. 2 is a plan view thereof. Fig. 3 is a side elevation showing the scraper in the act of dumping its load. Fig. 4 is a detail section illustrating the arrangement of rollers on the latch, tobe hereinafter described; and Fig. 5 is a fragmentary rear elevation of the bucket and coacting elements.

The bucket 6 has itsfront edge? inclined downward, so as to engage the earth and throw it rearward into the body of the bucket. The rear portion of the bucket is provided with two runners 8, respectively, at its side edges,

the runners serving to engage the earth and hold the bucket in position. The upper rear portion of the bucketismounted to swing on a transverse bar 9, which in turn is mounted in a frame composed of twoside bars 10. The rear portions of the side bars 10 have semicircular braces 11 secured thereto, as shown, and the front portionsof the side bars 10 project forwardly and downwardly and carry a roller 12, disposed transversely and having flanges le at its ends. These flanges engage the earth to hold the roller 12 in the proper line of movement. A bar 15 is extended transversely between and fastened to the side bars 10 just rearward of theroller 12 and carfries a scraper 16, engaging the roller to clean the surface thereof.

. Each side bar 10 is provided with a bracket 17,; which respectively carry the pivots 18 of latches 19. These latches are disposed vertically and have their lower extremities formed 7 with hooks 20, adapted to engage lugs 21, fastened to the respective sides of the bucket 6, at the front thereof, thus to limit the down-, ward movement of the bucket. The upper extremity of each latch 19 is formed with a housing 22, in each of which housings is mounted a roller 23 on a stationary journal and aroller 24; on a journalwhichis movable vertically in. slots formed in the housings, as shown best in Fig. at. The rollers 24 are arranged to drop by gravity toward the rollers 23, so that lines 25 passing between the rollers 23 and 21 will be held with some degree of firmness in connection with the upper ends of the respective latches 19. Each side bar 10 carries at its inner side, directly adjacent to the latches 19, rollers 26, which are two for each side bar, and arranged in pairs forming 75 guides, betweenlwhich the lines 25 may pass in a direction downward from the rollers 23 and 24. Additional rollers 27 are attached to the bucket 6 at the respective sides thereof and directly above the lugs 21, under which rollers the lines 25 pass. These lines are extended rearward and provided with stops28. The lines are rove through eyes 29, attached to therearof the bucket atthe sides thereof, and are passed rearward from the scraper to the point from which they are to be hauled, at which point any suitable means may be provided for drawing them. The lines 25 alsopass forward of the scraper to another distant point, where additional means are provided for hauling them. These hauling means may be of any .d esired sort and do not enter into my invention in any way. Lines 30 are attached to the front ends of the side bars 10 and pass forward in the same direction as the front ends of the lines 25.

In the operation of the invention, assuming that the parts are in the position shown in Figs. 1 and 2, the lines 30should be hauled,

thus drawing the scraper forward and causno ing the point 7 of the bucket 6 to plowinto the earth and throw the earth into the-bucket, during which operation the front end of; the bucket will draw downward until the'lu'gs 21 will engage with the latches19, thu slimitr05 ing the downward movement of the bucket.

position shown in Fig. 3.

When the bucket is full and it is desiredv to convey its load to the point at which it is to be dumped, the lines 30 are cast oif of the hauling apparatus and the lines 25- are hauled upon, thus causing thelines first to be drawn past the rollers 27, 26, 23, and 24, and finally engaging the stops 28 with the rollers 27 ,which prevents the further movement of the lines 25 independently of the scraper. This also lifts the front end of the scraper-bucket clear of the earth and permits the scraper to be moved over the earth with the rear portion only of the bucket engaged therewith. When the dump has been reached, the strain on the lines 25 should be slackened. Then the weight of the bucket will cause the front end to drop; but the frictional engagement of the gravityrollers 24: with the lines 25 will cause the upper ends of the latches to be thrown inwardly as the bucket drops, thus throwing the hooks 2O forwardly and placing them out of the line of the lugs 21, permitting the lugs to pass free of the hooks. Simultaneously with these operations the lines should be again hauled, which will advance the roller 12 and the frame of the scraper; but the front end of the bucket engaging the earth will cause the bucket to be thrown into the dumping Then to recover the operative position of the bucket the lines 25 should be hauled rearward, which will result first in the independent movement of the lines until the stops 2S engage the eyes 29 and also in the throwing forward of the lower ends of the latches 19. As soon as the stops 28 engage the eyes 29 the lines 25 will serve to draw the scraper rearward, thus throwing the bucket back to its normal position and permitting the lugs 21 to pass upward above the books 20 of the latches 19, thus placing the parts in the operative position shown in Fig. 1. The scraper may now be returned to the grading by drawing the scraper backward, as explained.

Having thus described my invention, I claim as new and desire to secure by Letters Patent 1. In a scraper, the combination with a frame, of a bucket mounted to swing thereon, a latch movably mounted on the frame and acting with the bucket to hold it in normal position, and means carried by the latch for frictionally engaging a line therewith, by which line the latch is actuated.

2. In ascraper, the combination of a frame, a bucket mounted to swing thereon, a latch pivotally mounted on the frame and working with the bucket to hold it normally in active position, a line passing by the latch, means on the latch for frictionally engaging the line with the same, an eye on the bucket, through which eye the line is rove, and a stop attached to the line intermediate the line and latch.

3. In a scraper, the combination of a frame, a bucket mounted to swing thereon, guide devices on the bucket, a line rove through the guide devices, a stop attached to the line intermediate the guide devices, a latch mounted pivotally on the frame and working with the bucket to hold it in normal position, the latch being engaged by the line, and means carried by the latch for frictionally engaging the line.

4. In a scraper, the combination ofa frame, a bucket mounted to swing thereon, a latch mounted on the frame and working with the bucket to hold it in operative position, and a roller mounted on the latch and movable vertically thereon, the roller being adapted to drop by gravity and formed with means for frictionally engaging a line with the latch.
